\ k j auromosins-wnnnn This invention relates -to automobile wheels and its object is to provide an improvement in the construction of said wheels, with a view to adapting the automobile for riding upon the rails of street railways or the usual railroad tracks, so that by providing an automobile with two sets of demountable rims, one of them adapted to be used in connection with pneumatic tires and the other, although not necessitating any change in the rim construction, being capable of engaging rails, the automobile provided with these two sets will be enabled to traverse both highways and run upon railroad tracks.

11 connection with the drawings: Figure 1 is a side elevation of the wheel constructed according to this invention.

Fig. 2 is a side elevation taken'from the Fig. 3 is a section taken along line 33 of Fig. 2.

Fi 4 is an enlarged detail of my method of mounting the rail tire upon the rim.

Fig. 5 is a perspective view of said 'rail tire.

Referring'more particularly to the drawings; it will be seen that in a wheel constructed in accordance with the present invention, conventional spokes 1 are provided which support the folly 2 upon which is cured the usual demounta le rim 3 provided with an upwardly extending flange 4. this flange being arranged as is usual, around the inner face of the wheel so that the movable wedges 8 may be readily accessible.

- The usual pneumatic tire is removed from the rim 3 andi a rail tire 5 is adapted, to be mounted upon the demountable mm 3 in place of the usual epneumatic tire, said rail tire 5 being form with an upwardly extending flange 6, adapted to engage the rail. It will be noted that the rail tire is of sub stantially twice the width of the rim 3 and that the thickness of said-tire decreases toward the edge opposite to the upturned flange 6, so that the outer periphery of the wheel may have a tapered form. By this construction it is possl le to obtain as large Specification of Letters Patent,

a tractionsurface as ossible for the tire, and the taperedjorm of the outer periphery of the time oifers a relatively sma contactmg surface between the tire and the rail, which is ,relatively small as compared with the area of the. 'eriphery of the tire 5, whereby the frictioiif etween the wheel and the-rail is greatly reduced.

The tire 5, as aforestated,,is disposed upon .the rim 3 and abuts against the flange 4. It

will be noted that I have provided the, tire with raised surfaces 7, upon its inner face. In positi'onlng m tireupon the rim I permi't the portions to come directly over the wedges 8 thereby providing that the portions of the: tire subjected tothe greatest stress are "provided with the 'eatest strength. .The wedges 8 are provide with a right angle extension 9 adapted to overlap the felly 2 upon one of its sides. The outer surface of the rim 3 at the flange 4 is made convex as indicated'at 14 and a boltll is provided, formed with 'a head 13, having one of its edges made concave so as to lie snugly against the outer surface of the rim 3 at 14.

The bolt 11 is screw threaded at its opposite end and after a washer 10 has been interposed between the side of the felly 2 and the right angle extension 9 of the wedge 8, a nut 12 is adapted to be applied to said threaded portion and u on tightening, to

bolt the wedge 8, inwa y, thus firml en gaging the portions 7 of the tire 5 an preventing-any movement of this wheel with respect to the rim. It will be further noticed that upon this operation taking place, the tire 5 will bear very strongly against the upturned flange 4 and this an additional brace for-the flange 4.

Having thus described my invention, what I claim is 1. A wheel including a folly, a rim secured thereon and formed with an upwardly extended flange along its inner edge, a rail tapered flanged tire moun' on said rim against the flan I thereof and extending from the outer si e of the wheel, a lurality of wedge-shaped members direeti; interpnsed Befiweem flies thneredl tire? andi at!- the out izaa'zedge: :5= thee lhtberg. each verifiesshafiged memberrbeingmrovidedhvithwr1 11%;?
